Biology

Snapping shrimps or pistol shrimps are immediately distinguished by having one claw much larger than the other, the larger claw cylindrical and with a parrot-beak-like finger. The Narrow Snapping shrimp is so named because the large claw is laterally compressed. The shrimp usually lives in pairs, often in the burrow made by the file shell, Limatula strangei, a bivalve said to be distasteful to fish.
